Welcome back. What was your level when you quit? You say you need to re-learn carve gybes, were you 100% sure in your waterstarts? If yes then you can maybe go a bit smaller than you think (and the wind is reliable). To be on the safe side for uphauling/schloging, you will need around 120/125 litres of volume, but you will lose a bit of the higher wind range and in lumpy water. What are your typical conditions/sail sizes? (and please don't say from 3 to 7bf ;-))), choose what's the most frequent and/or the most important)
